How is Auto ISO these days?

The camera should have four modes:

M - dials work as they do now.
Av - Main dial for aperture, QCD for ISO. EC requires a button press.
Tv - Main dial for shutter, QCD for ISO. EC requires a button press.
X (aperture + shutter mode) - Main dial for shutter, QCD for aperture, EC requires a button press.

Sounds good to me! Obviously you've put much more thought into this than me.

Yes, that is how it works. Put the camera in M mode and set the ISO to A. Then you set the aperture and shutter speed manually and the camera will pick the ISO to center the meter.

But it will literally center the meter. You cannot set any exposure compensation because (slaps forehead) you are in M mode.

There is a way to set something close to EC on the 1D4, just add the AE micro adjust to your My Menu. Works well enough, it is just not that convenient.

the 7d has a very good Auto ISO mode also.
You can set the upper limit now (with the firmware update)

I use it all the time in Manual mode as Jeffrey described.
its awesome for wildlife/birds because you have no time to adjust sometimes.

so, i set my shutter to what Im shooting (still or flight)
set my aperture for the desired DOF
auto ISO
and bingo, my pics are pretty darn good.

Auto ISO on my 1DMkIV worked surprisingly well on a night-time walkabout not too long ago...

Did its level best to keep me hand-holdable with a 50mm f/1.4 mounted.

That is to say, it did the best it could to keep me at around 1/30

The title says it all. Just wondering how far auto ISO has come in recent bodies?

I've only ever owned a 40D and a 5Dc so I was curious if this feature actually works on newer bodies.

Here's what happens when Auto ISO is used on a 60D.

Byte size: ZERO | Content warning: NOT AN IMAGE

Use it quite a bit on my 7D for video

I also only use auto ISO for video. Seems to work OK.

Auto ISO on my 5D3 works pretty smoothly. It's a handy feature in M mode, but I find myself setting a specific ISO in M mode in order to get consistent exposures.

How do guys manage ETTR with M mode and auto ISO.

You don't, at least not with a 5D3 or 7D. You get an exposure with the meter centered, since there is no exposure compensation.

As was mentioned earlier, there is a workaround with the 1D4 where you can set a meter offset (a form of exposure compensation) within the custom functions. But this is pretty clunky and discourages adjusting the meter offset while working.

nice pics DC fan, thanks for sharing.

... I think it would be nice to have a dedicated dial for changing ISO.

Maybe I'm too much of a spoiled digital amateur, but wouldn't it be nice to have a dial to turn for ISO just like there is for aperture and shutter speed. It's kind of annoying to toggle back and forth with button pushes. Sure it's doable as is, and I've grown accustomed to the way it is, but...

Buy a 60D. Press one button, turn either dial and you can change ISO. Not exactly what you asked for, but the best Canon offers at the moment. All the 60D's top-deck buttons are single function. I think the 6D is the same.

Like it a lot on my 5D3 but why the heck did they have to limit the max shutter speed to 1/250? Ok for shorter lenses but longer lenses shooting with 22 megapixels, that limit can begin to become a problem, especially for when you need to freeze action. Why would they have to limit it? What possible point could there be?

I am not sure, because I don't own a 5D3, but that makes no sense to me. I can use Auto-ISO on my 60D and select any shutter speed from 30 seconds to 1/8000. My guess is that there is a custom function that limits the shutter speed. If that is NOT the case, you are certainly doing something improperly.

EDIT: Even my T1i allowed any shutter speed in Auto-ISO. It just locked you at ISO 400 in manual mode, which actually was stupid. Manual mode is where auto-ISO is most useful.

surely youre using flash which is causing that? You could use HSS to allow the faster shutter speeds be useable.

Exactly. That's how (AE micro adjust) I get exposure compensation during auto ISO on the 1D IV and 1D X.

It works great.
